Niemann-Pick disease (NPD) is a rare, inherited, autosomal recessive, lipid storage disease. The pathognomonic intracellular accumulation of sphingomyelin results in the production and accumulation of 'foam cells'. Interstitial lung disease is a rare manifestation of NPD. We present the case of a 48-year-old white female with NPD involving the lungs, liver and spleen. The chest radiograph showed bilateral, predominantly basal reticulonodular infiltrates and serial pulmonary function tests over a period of years showed preserved expiratory airflow and a severely decreased diffusion capacity for carbon monoxide (DLCO). In view of her visceral involvement, lack of neurological symptoms and survival into adulthood, we believe our patient represents a case of type B NPD. In this type of NPD, aside from prominent hepatosplenomegaly and sexual immaturity, significant pulmonary infiltration with 'Pick cells' has been reported. To date, no therapeutic modality has been shown to alter the natural history of this disease, which results in progressive debilitation and death. This case is unique in that it provides the longest physiological follow-up in the literature, and provides data on the natural history of pulmonary involvement in NPD.

The therapeutic field of in utero transplantation of stem cells, into human fetuses, has developed since 1988 with the hope of improved probability of engraftment and tolerance, due to immune immaturity of the host. Fifteen years later, it is possible to evaluate the results that we and others have obtained in the treatment of several fetal diseases. Seven fetal patients have been treated in Lyon: In 2 cases, pregnancy termination was induced by the in utero injection; in the 5 other cases, engraftment was obtained and repeatedly documented with presence of donor HLA antigens and/or Y chromosome in recipients. In the 2 patients with combined immunodeficiency disease, a sustained reconstitution of immunity was obtained as a result of the transplant but other complications occurred thereafter. In patients with thalassemia major, Niemann-Pick disease or hemophilia, a very partial and very transitory benefit was only obtained. Approximately 33 other patients with immunodeficiencies, hemoglobinopathies or inborn errors of metabolism have been treated worldwide, over the last 13 years, with a comparable method, using parental or fetal stem cells transplanted in utero. Successful treatment has usually been recorded in immunodeficiencies, and insufficient results have been obtained in the other cases. This form of treatment can therefore be recommended after prenatal diagnosis of combined immunodeficiency but additional research is required to improve the degree of engraftment, the lack of resistance of the host and the 'space' available for hematopoiesis in the other conditions.
